blx: Battery Life eXtender (BLX)

This is a simple port of Ezekeel's BLX mod to the Nexus 4.

See this thread for more information: http://forum.xda-developers.com/showthread.php?t=1257497

Let's keep the same sysfs implementation so that apps, such as Trickster MOD, can support this.

ak_mako_defconfig: enable BLX

cpufreq: interactive: fix show_target_loads and show_above_hispeed_delay

Remove a trailing whitespace from target_loads and above_hispeed_delay. Problem
happens when user-space program tried to restore parameters that saved before
changing parameters. In this case was returned error(EINVAL).

cpufreq: interactive: Remove unnecessary cpu_online() check

Cpufreq no longer calls governor callback for offlined cpus. i.e. All
policy->cpus are guaranteed to be online. Hence we don't need explicit check to
see if cpu is online or not.
